Thanks, Actually, I am lost. I am upgrading one of the systems on a multi-disks system. 1) I realized that one system is not efi, while the other ones are. 2) After I upgraded this system. I can boot it, but it is weird. a) There was no update of the grub menu (I boot fc32, while the invitation is still fc30) b) grub2-mkconfig has not been run c) grub2-mkconfig (manually) did not recognized by the booted system except through set root='hd2,msdos3', but no menuentry for this system.
